Function
LPQN_MYCTU Involved in cell envelope biogenesis. May act as a membrane fusion protein, connecting MmpL transporters with periplasmic proteins, and play a role in cell envelope lipid changes during biofilm maturation.[1] Is also a virulence factor required for intracellular survival (PubMed:30118682). Associates with CBL, a host ubiquitin ligase, and probably blocks the normal functions of CBL and disturbs CBL-mediated antibacterial activity (PubMed:30118682). Interaction counteracts antibacterial defense but causes a reciprocal enhancement of antiviral defense (PubMed:30118676, PubMed:30118682).[2] [3]
